[0031] As shown in Figure 5 , the suction interface 411 is in a bare state when the device is not in use, which has the risk of being contaminated.

[0032] The present application shows a device interface anti-pollution anti-bare protective sleeve, two specific embodiments are described below.

[0033] Embodiment one

[0034] Referring to Figure 1 , Figure 3 and Figure 5 , a device interface anti-pollution anti-bare protective sleeve is described, including a tie 100, a connecting rope 211 and a sleeve assembly 300.

[0035] The two ends of the tie 100 are connected to form a fixed collar 101, so that the tie 100 is sleeved at the root position of the suction interface 411.

[0036] The sleeve assembly 300 includes a sleeve body 311, which has a receiving cavity 312 for sleeving the end position of the suction interface 411. The sleeve body 311 is a member of elastic material, so that the inner wall of the sleeve body 311 is pressed against the outer wall of the suction interface 411 after the sleeve body 311 is sleeved on the suction interface 411.

[0037] The tie 100 is provided with a first connecting portion, and the sleeve body 311 is provided with a second connecting portion 331. One end of the connecting rope 211 is connected to the first connecting portion, and the other end of the connecting rope 211 is connected to the second connecting portion 331.

[0038] It can be understood that the sleeve body 311 is used to seal the suction interface 411, which can prevent the suction interface 411 from being contaminated. The sleeve body 311 is a member of elastic material, specifically a member of silicone material, which can be pressed against the outer wall of the suction interface 411 when in use, thereby playing a sealing role. In addition, the tie 100 is designed to be able to be sleeved at the root position of the suction interface 411 after the two ends are connected, which can be adapted to different specifications and sizes of the suction interface for fixation. The sleeve body 311 is connected to the tie 100 through the connecting rope 211, which can prevent the sleeve body from falling off.

[0039] In the prior art, the outer wall of the suction interface 411 is provided with a plurality of annular mounting flanges 412 to facilitate the use of the suction tube and make the installation more secure. If the inner diameter of the sleeve body 311 is designed to be too small, it will be difficult to fit the suction interface 411 due to the annular mounting flanges 412, and if the inner diameter is designed to be too large, the outer wall of the suction interface 411 cannot be compressed tightly, and the sealing state cannot be achieved. Therefore, in this embodiment, a plurality of sealing annular flanges 313 are arranged on the inner wall of the sleeve body 311 along the length direction. Assuming that the inner diameter of the sleeve body 311 is too large, but because the sealing annular flanges 313 are designed, the sealing annular flanges 313 can be compressed tightly on the outer wall of the suction interface 411, thus ensuring the sealing between the suction interface 411 and the sleeve body 311. It can be understood that the suction interface specifications that the sleeve body 311 can adapt to can be wider.

[0040] In addition, the spacing between adjacent two sealing annular flanges 313 is defined as d, and each d is not equal. It can be understood that because the outer wall of the suction interface 411 is provided with a plurality of annular mounting flanges 412, there will be a groove between adjacent annular mounting flanges 412 to avoid the sealing annular flanges 313 being stuck at the position of the groove and unable to play the role of the sealing annular flanges 313. Therefore, by setting the spacing between the sealing annular flanges 313 to be unequal, this situation can be avoided.

[0041] Of course, in the case of a suction interface with a smooth outer wall, a plurality of sealing annular flanges 313 are arranged on the inner wall of the sleeve body 311 along the length direction. Similarly, the local elastic deformation of the sealing annular flanges 313 at this position can be increased, and the compression force of the outer wall of the suction interface 411 can be increased, which can further prevent the suction interface 411 from falling off.

[0042] In addition, in order to facilitate the insertion and removal of the sleeve body 311, at least one auxiliary holding wing 321 is arranged on the outer wall of the sleeve body 311 in this embodiment to facilitate gripping when the sleeve body 311 is taken out. The auxiliary holding wing 321 is specifically provided with two and symmetrically arranged on both sides of the sleeve body 311.

[0043] Further preferably, a plurality of anti-slip protrusions 322 are arranged on the two end faces of the auxiliary holding wing 321 to increase the anti-slip effect when gripping. In addition, notches 323 are arranged at the front and rear ends of the auxiliary holding wing 321, and in the use process, the fingers can be placed at the position of the notches 323 to exert force, making the insertion and removal easier.

[0044] The following will be described with reference to Figure 3The specific structure of the cable tie 100 in this embodiment is described in detail. The cable tie 100 includes a cable tie head 121 and a cable tie body 111 connected to the cable tie head 121. A first connecting part is provided on the cable tie head 121. The cable tie head 121 is provided with a rope hole 122. The cable tie head 121 is provided with a locking part 124 at the position of the rope hole 122. The cable tie body 111 is provided with a plurality of anti-retraction protrusions 112 along the length direction. The end of the cable tie body 111 is inserted into the rope hole 122 of the cable tie head 121 and then connected. The locking part 124 locks the anti-retraction protrusions 112 to limit the fixing collar 101. Furthermore, both the cable tie head 121 and the cable tie body 111 are plastic components. The cable tie head 121 is provided with a pressing block 123, the middle of which is connected to the cable tie head 121. A locking part 124 is provided at one end of the pressing block 123 near the rope hole 122, and an unlocking part 125 is provided at the other end of the pressing block 123. The cable tie body 111 is strip-shaped. After the cable tie body 111 is inserted into the rope hole 122, the anti-reverse protrusion 112 faces the pressing block 123. By pressing the unlocking part 125, the pressing block 123 is deformed, thereby causing the locking part 124 to disengage from the anti-reverse protrusion 112.

[0045] Understandably, during use, the cable tie body 111 is bent around the root of the suction connector 411, and then the end of the cable tie body 111 is inserted into the threading hole 122 of the cable tie head 121. When the fixing collar 101 is adjusted to the required position, the locking part 124 locks the anti-retraction protrusion 112, limiting the size of the fixing collar 101. When removal is required, the cable tie body 111 does not need to be interrupted. The unlocking part 125 of the pressing block 123 can be pressed, the pressing block 123 deforms, the locking part 124 disengages from the anti-retraction protrusion 112, and the cable tie body 111 can be pulled out from the threading hole 122, thus achieving detachment. In practical applications, when the cable tie body 111 is straight and not bent, the anti-retraction protrusion 112 is inclined towards the end away from the cable tie body 111. When the end of the cable tie body 111 is inserted into the threading hole 122 of the cable tie head 121, as... Figure 3 As shown, during insertion, the inclined surface of the anti-retraction protrusion 112 can push up the locking part 124 and is not locked by the locking part 124. During disengagement, the inner side of the inclined surface of the anti-retraction protrusion 112 presses against the locking part 124, at which time the anti-retraction protrusion 112 is locked by the locking part 124.

[0046] In some embodiments, the unlocking part 125 may not be provided. In this case, if the cable tie 100 needs to be removed, the cable tie body 111 needs to be cut short.

[0047] exist Figure 3 The first connecting part is not shown in the figure. The first connecting part is located on one side of the cable tie head 121 and is positioned opposite to the pressing block 123.

[0048] Example 2

[0049] Referring to Figure 2 , Figure 4 and Figure 5 , a device interface anti-pollution anti-bare protection sleeve is shown. This embodiment is different from embodiment one in the specific structure of the cable tie 100.

[0050] In this embodiment, as shown in Figure 4 , the cable tie 100 includes a cable tie head 121 and a cable tie body 111 connected with the cable tie head 121, a first connecting part 131 is arranged on the cable tie head 121, the cable tie head 121 is provided with a rope passing hole 122, the cable tie head 121 is provided with a locking part 124 at the position of the rope passing hole 122, the cable tie body 111 is provided with a plurality of retreat stop protruding parts 112 along the length direction, the end of the cable tie body 111 is connected after being inserted into the rope passing hole 122 of the cable tie head 121, and the locking part 124 clamps the retreat stop protruding part 112 to limit the fixed ferrule 101.

[0051] In this embodiment, the cable tie head 121 and the cable tie body 111 are both rubber members, specifically silicone members, wherein the cable tie body 111 is a round strip, the diameter of the rope passing hole 122 is greater than the diameter of the cable tie body 111, and the retreat stop protruding part 112 is an annular clamping flange arranged on the cable tie body 111, and the diameter of the rope passing hole 122 is smaller than the diameter of the retreat stop protruding part 112.

[0052] It can be understood that in use, the cable tie body 111 is bent around the root position of the suction connector 411, and then the end of the cable tie body 111 is inserted into the rope passing hole 122 of the cable tie head 121. Since the diameter of the rope passing hole 122 is smaller than the diameter of the retreat stop protruding part 112, it needs to be pulled with force, and the retreat stop protruding part 112, that is, the annular clamping flange, will be elastically deformed, and then pass through the rope passing hole. When the fixed ferrule 101 is adjusted to the required position, since the diameter of the rope passing hole 122 is smaller than the diameter of the retreat stop protruding part 112, the retreat stop protruding part 112 is clamped by the rope passing hole 122 without external force, that is, the fixed ferrule 101 is limited.

[0053] Specifically, the size of the rope passing hole 122 is gradually expanded from the middle to both ends, and the cable tie head 121 is formed with the locking part 124 at the middle position of the rope passing hole 122.

[0054] The structure of the cable tie 100 of embodiment two is very fast to disassemble and assemble, and the overall weight of the sleeve assembly 300 is not large. In actual application, the structure of the cable tie 100 of embodiment two can be used to facilitate the use of medical workers.

[0055] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
